Frederick Frost Blackman FRS[1] (25 July 1866 – 30 January 1947) was a British plant physiologist.
In the subsequent years, he studied natural sciences at the University of Cambridge and was awarded DSc.
Gabrielle Matthaei was his assistant until 1905; her laboratory work underpinned much of the theory of FF Blackman’s Law of Limiting Factors (below).
Their collaboration ended in 1905 when Gabrielle married Albert Howard, thereafter supporting his work as Imperial Economic Botanist to the Government of India.
[4] The two men, and FF’s brother, Vernon Blackman (another botanist), had become friends while students at Cambridge.
FF Blackman was buried at the Parish of the Ascension Burial Ground in Cambridge, with his wife Elsie (1882–1967).
